Anyone who has read my coloring book reviews knows I speak the highest of books from Bellerphon Press. (and Troubador Press) as these coloring books are print on the best qulaity paper for colored pencils. A heavy, toothy paper which takes colored pencils, and markers exceptionaly well. These books are illustrations, combined with the history of said subject matter, which makes them good for not just coloring, but also for home schooling, or research. Or for anyone (such as myself) who enjoys learning something of what they are coloring. Difficult to find, and often expensive for a new unused copy. Usually these are only available thru Amazon, via third party vendors. I happened to score this paticular coloring book for a mere 4.00$, a brand new copy, which often times these copies deemed 'brand new' start at 25.00, or 35.00 dollars. If you LOVE coloring in a quality coloring book, THESE are the books for you!
